PAUT Corrosion Mapping Services

This platform is exclusively developed to present our specialized PAUT inspection services, and corrosion mapping is one of the most valuable applications within our advanced inspection portfolio. Our PAUT corrosion mapping solutions are designed to support condition evaluation, wall loss assessment, preventive maintenance planning, and asset reliability improvement across a wide range of industrial assets.

Backed by field experience, technical capability, and a wider background in inspection and integrity services, we help clients maintain safety, compliance, operational continuity, and long-term asset performance through dependable corrosion assessment solutions.

What Is PAUT Corrosion Mapping?

PAUT Corrosion Mapping is an advanced ultrasonic inspection method used to assess wall thickness variations and identify localized or general material loss across components such as pipes, vessels, tanks, and structural sections. Unlike spot thickness checks, phased array corrosion mapping allows broader area coverage and provides a more detailed picture of the asset condition.

This technique is highly useful for detecting and evaluating:
➤ General wall thinning
➤ Localized corrosion
➤ Erosion damage
➤ Pitting-prone regions
➤ Internal metal loss
➤ External wall loss
➤ CUI-prone condition screening support
➤ Remaining thickness trends
➤ Critical thinning zones requiring further evaluation

PAUT corrosion mapping helps clients move beyond isolated thickness readings and obtain a more meaningful understanding of the actual condition of the component surface or section under inspection.

Our PAUT Corrosion Mapping Capability

At NDT AND PWHT Solutions Pvt Ltd, our corrosion mapping services are delivered with a practical and engineering-oriented approach based on asset type, access conditions, surface condition, material thickness range, and inspection objectives. We support both planned condition assessment programs and shutdown-based inspection campaigns for critical plant assets.

Our approach focuses on generating dependable thickness distribution information to support:
➤ Corrosion monitoring
➤ Integrity screening
➤ Maintenance planning
➤ Repair prioritization
➤ Shutdown scope development
➤ Fitness-for-service review support
➤ Asset life extension strategies

We understand that corrosion is not always uniform, and that critical metal loss can occur in isolated or difficult-to-predict areas. Our mapping approach helps improve confidence in inspection coverage and decision-making.

Applications of PAUT Corrosion Mapping

Our PAUT Corrosion Mapping Services are suitable for a wide range of industrial inspection applications, including:

General Corrosion Assessment

Evaluation of wall loss across process assets to identify general thinning and determine the overall condition of the component.

Localized Corrosion Screening

Inspection of critical zones where corrosion or erosion may be concentrated due to flow conditions, process environment, or service exposure.

In-Service Condition Monitoring

Support for ongoing operation and maintenance programs by tracking wall thickness changes and identifying deterioration before it becomes critical.

Shutdown Inspection Programs

Detailed corrosion assessment during shutdowns and turnarounds to support repair planning, replacement decisions, and integrity review.

Preventive Maintenance Planning

Providing meaningful thickness mapping data that helps maintenance teams prioritize intervention and optimize inspection intervals.

Integrity Assessment Support

Assisting engineering and asset integrity teams with better condition visibility for evaluation of remaining strength, future monitoring, and risk-based inspection planning.

Components We Commonly Inspect

Our PAUT corrosion mapping services can be applied to a wide range of industrial assets, including:
➤ Pipelines
➤ Process piping
➤ Pipe spools
➤ Pressure vessels

Why Choose Our PAUT Corrosion Mapping Services?

Better Area Coverage

Unlike isolated spot readings, PAUT corrosion mapping provides improved coverage across larger or critical areas, helping identify thickness variations more effectively.

More Meaningful Condition Evaluation

Corrosion damage is not always uniform. Mapping helps reveal thickness trends, isolated thinning areas, and critical loss zones that may be missed by limited-point inspection.

Practical Maintenance Value

Our corrosion mapping services help clients make better maintenance, repair, replacement, and monitoring decisions based on actual asset condition.

Strong Integrity Background

As a company active in integrity inspection and preventive maintenance support, we understand that corrosion data must be useful for operational planning, not just inspection records.

Suitable for Critical Assets

Our services are aligned to the needs of clients managing safety-critical and production-critical assets where wall loss directly affects reliability and risk.

Clear Reporting Support

We aim to provide structured results that support engineering interpretation, maintenance planning, and asset condition review.

Service Scope Highlights

Our PAUT Corrosion Mapping Services may include:
➤ Inspection planning and coverage strategy development
➤ Identification of critical inspection zones
➤ Surface condition review and scanning feasibility assessment
➤ Selection of suitable probes, wedges, and scanning methods
➤ Manual or encoded corrosion mapping, based on project requirement
➤ Thickness distribution assessment
➤ Identification of localized and general wall loss zones
➤ Support for comparison with nominal thickness or previous inspection data
➤ Inspection reporting and technical documentation
➤ Coordination with maintenance, inspection, and integrity teams

Value to Clients

Through our PAUT corrosion mapping services, we help clients achieve:
➤ Better understanding of actual wall condition
➤ Improved visibility of corrosion-prone areas
➤ More informed repair and maintenance planning
➤ Reduced uncertainty in remaining thickness evaluation
➤ Better support for shutdown and turnaround decisions
➤ Improved asset integrity management
➤ Greater confidence in operational safety and reliability
